Description

Technical Field

[0001] This utility model belongs to the field of carpet production technology, specifically relating to an integrated carpet composite drying oven. Background Technology

[0002] Carpet lamination is a process that combines multiple layers of materials to create a carpet, typically including a surface fiber layer, a middle cushioning layer, and a bottom anti-slip layer. This structure increases the carpet's comfort, durability, and stability.

[0003] In actual production, hot melt powder (EVA) is evenly sprinkled onto the carpet using a combination of powder rollers and sieves. After the EVA is sprinkled onto the bottom layer of carpet, it is baked in an oven until the hot melt powder reaches a molten state. Then, it is pressed together with another layer of carpet to form a composite carpet. When laminating carpets of different materials, the heating distance between the heating plate and the carpet needs to be adjusted. Due to the relatively long length of the heating plane, the current lifting mechanism causes asynchronous lifting distances at the four corners of the heating plane, which can easily lead to deformation of the entire heating plane, resulting in uneven heating of the carpet and adhesion defects between the layers of the produced composite carpet. Therefore, a new type of integrated carpet laminating oven is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses an integrated carpet composite drying oven.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An integrated carpet composite drying oven includes two parallel rows of support frames. Several transmission rollers are rotatably mounted on both rows of support frames, and a Teflon conveyor belt is fitted onto each of the transmission rollers. A drying rack is connected to the top of both rows of support frames, and a lifting mechanism is installed on the top of the drying rack. The lifting mechanism includes a control motor fixedly mounted on the top of the drying rack. The output end of the control motor drives a worm gear reducer. An output connecting rod is coaxially fixedly inserted into the output ring of the worm gear reducer. Connecting rods are coaxially and linearly inserted into both ends of the output connecting rod. Each connecting rod is coaxially connected to a transmission device, and a connecting rod is coaxially fixedly inserted into the two output ends of each transmission device. A screw jack is coaxially fixedly inserted into the end of each connecting rod away from the transmission device. The output end of each screw jack vertically penetrates the drying rack, and the output ends of the four screw jacks are connected to a connecting plate. Several heating plates are arranged at the bottom of the connecting plate.

[0007] In a preferred embodiment of this invention, the axis of the transmission roller is perpendicular to the extension direction of the support frame.

[0008] As a preferred embodiment of this utility model, the output ends of the four screw jacks are respectively fixedly connected to the four corners of the connecting plate.

[0009] As a preferred embodiment of this utility model, the plug-in connecting rod is provided with a linear groove parallel to its own axis, and the output connecting rod is provided with a linear protrusion adapted to the linear groove.

[0010] As a preferred embodiment of the present invention, a drive motor is coaxially fixedly connected to the end of some of the transmission rollers, and the drive motor is fixedly connected to a second mounting base, each of the second mounting bases being fixedly connected to an adjacent support frame.

[0011] As a preferred technical solution of this utility model, a plurality of pin hanging mechanisms adapted to the edge of the Teflon conveyor belt are respectively provided on both sides of the Teflon conveyor belt, and the pin hanging mechanisms are symmetrically arranged about the Teflon conveyor belt.

[0012] As a preferred technical solution of this utility model, each of the needle hanging mechanisms includes a mounting plate on the top of the mounting support frame, a double-acting cylinder is mounted on the bottom of the mounting plate, and a slider is slidably connected to the top slide rod of the mounting plate. The piston rod of the double-acting cylinder is fixedly connected to the slider. The slider is laterally rotatably connected to a needle roller. The axis of the needle roller is perpendicular to the conveying direction of the Teflon conveyor belt, and the needle roller is set at the edge of the Teflon conveyor belt.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This application adjusts the heating distance between the heating plate and the carpet by setting up a lifting mechanism. Because it adopts a driving method of one control motor driving four screw jacks and a connecting rod and gear connection method, it can realize the simultaneous adjustment of the four screw jacks, reduce the asynchronous adjustment of the four corners caused by the gear or elastic gaps of using chains or timing belts, and ensure the flatness of the heating surface.

[0015] 2. In the lifting mechanism of this application, both ends of the output connecting rod are coaxially and linearly connected to the plug-in connecting rod, so that the overall length of the output connecting rod and the two plug-in connecting rods is adjustable, which can match heating planes of different lengths and improve the versatility of the equipment.

[0016] Third, when this application is used to composite a shrinkable and needle-punched carpet, the piston rod of the double-acting cylinder contracts, causing the slider to move down and the needle roller to pierce the lower carpet layer. The needle is hung on the edge of the lower carpet layer, and the carpet width is kept from becoming uneven due to shrinkage during operation. Attached Figure Description

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] Please see Figure 1-6 An integrated carpet composite drying oven includes two parallel rows of support frames 1, with several drive rollers 2 rotatably mounted on both rows of support frames 1. Bearings are coaxially fixed at the ends of each drive roller 2, and the bearings at the ends of the drive rollers 2 are respectively embedded in through holes of a first mounting seat 8 or a second mounting seat 9 fixedly mounted on the support frames 1. A Teflon conveyor belt 3 is mounted on the several drive rollers 2, with the axis of the drive rollers 2 perpendicular to the extension direction of the support frames 1. The Teflon conveyor belt 3 uses a 5mm large-aperture Teflon mesh. An oven rack 5 is connected to the top of both rows of support frames 1, and a lifting mechanism 6 is installed on the top of the oven rack 5. Several oven doors 10 are installed on both sides of the oven rack 5.

[0030] The lifting mechanism 6 includes a control motor 601 fixedly installed on the top of the oven rack 5. The output end of the control motor 601 drives a worm gear reducer 602. An output connecting rod 603 is coaxially fixedly inserted into the output ring of the worm gear reducer 602. Connecting rods 604 are coaxially and linearly inserted into both ends of the output connecting rod 603. Each connecting rod 604 is coaxially connected to a transmission device 605, and each of the two output ends of the transmission device 605 is coaxially fixedly connected to a connecting rod 606. The input end of the transmission device 605 transmits power to both output ends simultaneously via a bevel gear. A screw jack 607 is coaxially fixedly inserted into the end of each connecting rod 606 away from the transmission device 605. The output end of each screw jack 607 vertically penetrates the oven rack 5, and the output ends of all four screw jacks 607 are connected to a connecting plate 11. Specifically, the output ends of the four screw jacks 607 are fixedly connected to the four corners of the connecting plate 11. Several heating plates 12 are arranged at the bottom of the connecting plate 11. Since the input ends of the four screw jacks 607 are driven in different directions, it is necessary to select screw jacks 607 with different driving directions as needed, so that the output ends of the four screw jacks 607 can extend and retract synchronously under the drive of a control motor 601.

[0031] The heating plate 12 is an infrared heating plate, and the heating tubes are all embedded in the heating plate 12. The distance between the heating tubes and the carpet surface can be adjusted according to production requirements.

[0032] The plug-in connecting rod 604 is provided with a linear groove parallel to its own axis, and the output connecting rod 603 is provided with a linear protrusion that matches the linear groove. The plug-in connecting rod 604 can only slide linearly relative to the output connecting rod 603, thereby accommodating connecting plates 11 of different lengths.

[0033] A drive motor 4 is coaxially fixedly connected to the end of a portion of the transmission roller 2, and the drive motor 4 is fixedly connected to a second mounting base 9. Each second mounting base 9 is fixedly connected to an adjacent support frame 1. The drive motor 4 drives the portion of the transmission roller 2 to rotate, thereby driving the Teflon conveyor belt 3 to run.

[0034] Several pin hanging mechanisms 7 adapted to the edges of the Teflon conveyor belt 3 are respectively provided on both sides of the Teflon conveyor belt 3, and the pin hanging mechanisms 7 are symmetrically arranged about the Teflon conveyor belt 3.

[0035] Each needle-hanging mechanism 7 includes a mounting plate 701 on top of a mounting support frame 1. A double-acting cylinder 702 is mounted on the bottom of the mounting plate 701, and a slider 703 is slidably connected to the top slide rod of the mounting plate 701. The mounting plate 701 can be directly mounted on the support frame 1 or indirectly connected to the support frame 1 via a second mounting seat 9. The piston rod of the double-acting cylinder 702 is fixedly connected to the slider 703. A needle roller 704 is laterally rotatably connected to the slider 703. The axis of the needle roller 704 is perpendicular to the conveying direction of the Teflon conveyor belt 3, and the needle roller 704 is located at the edge of the Teflon conveyor belt 3. The rotating shaft of the needle roller 704 is rotatably connected to the slider 703 via bearings.

[0036] Working principle:

[0037] During carpet lamination, the Teflon conveyor belt 3 transports the lower carpet layer, whose upper surface is evenly covered with hot melt powder, to below the heating plate 12. As the lower carpet layer passes the heating plate 12, the hot melt powder is heated and melted. Then, the lower carpet layer is transported away from the heating plate 12 and simultaneously pressed together with the upper carpet layer that is being driven down from the upper layer. After being rapidly and forcibly cooled and shaped, a composite carpet with sufficient strength is formed.

[0038] When carpets made of different composite materials are used, the distance between the heating plate 12 and the lower carpet layer varies, and this is adjusted by the lifting mechanism 6. The control motor 601 drives the output connecting rod 603 to rotate through the worm gear reducer 602. The output connecting rod 603 drives two transmission devices 605 through two plug-in connecting rods 604 at both ends. Each transmission device 605 drives the screw jack 607 through the connecting rod 606, which is coaxially fixedly plugged into its two output ends. Because a driving method of one control motor 601 driving four screw jacks 607 and a connecting rod and gear connection method are used, the four screw jacks 607 can be adjusted synchronously, reducing the asynchronous adjustment phenomenon at the four corners caused by the gear or elastic gaps of using chains or timing belts.

[0039] When laminating a shrinkable and needle-punched carpet, the piston rod of the double-acting cylinder 702 retracts, causing the slider 703 to move downwards. The needle roller 704 then inserts into the lower carpet layer, hooking the needles along the edges of the lower carpet layer. The needle roller 704 rotates as the lower carpet layer moves, ensuring that the carpet width does not become uneven due to shrinkage during operation. When laminating a non-needle-punched carpet, the needle roller 704 rises.

[0040] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
